RFR: JDK-8033236 Update GensrcCharsetMapping.gmk to build-infra standards

[Xueming Shen]

Changeset looks fine. Thanks for doing this.

Potentially it might worth considering to move two template files
DoubleByte/SingleByte-X.java.template into the corresponding source
code directory as well. But they can be dealt with later. We should
migrate the StandardCharsets generating code from awk/sed to Java
someday as well.

Similar to the compile constructs, we can setup a file (or a bunch of files) which needs different kinds of text transformations. In this case, only the INCLUDE functionality is used.
